What food and nutrition services should be regulated in assisted-living facilities for older adults? - Journal of the American Dietetic Association
The opinions of both national aging and health experts and practicing registered dietitians (RDs) were surveyed on which key quality indicators from the Food And Nutrition Care Indicators checklist should be regulated in assisted-living facilities (ALFs) for older adults. The extent to which the practices on which the indicators were based should be regulated, and which were in fact included in the current regulations of the 50 states was also studied. One hundred fifty-three national aging and health experts were surveyed in 2005 and 882 practicing RDs who were members of two American Dietetic Association dietetic practice groups employed in ALFs were surveyed in 2006. Both the experts and the RDs believed that the need for regulations in ALF food and nutrition services was vital for about a third of the indicators, (eg, 18 items on the 57 item checklist), particularly those involving facilities and staffing. For seven out of the 18 indicators, there was substantial consensus between experts and RDs. Only three of the seven indicators were addressed by regulations in more than half of the states. Consensus exists among experts and RDs that a small but significant number of food and nutrition service indicators need to be regulated.
Experts stress both wellness and amenity aspects of food and nutrition services in assisted living facilities for older adults. - Journal of the American Dietetic Association
There has been no consensus on best practices in food and nutrition services in assisted living facilities for older adults. We documented experts' views on optimal food and nutrition services emphases in assisted living facilities, and factors affecting their views.One hundred thirty-five national experts specializing in health, aging, nutrition and assisted living facilities completed a survey consisting four scenarios (ie, home-style, restaurant/hotel, and health/medical, and a combination of these three) in six food and nutrition services areas: dining room environment, meal services, meal quality, nutrition services, employees' qualifications, and therapeutic nutrition services.Sixty-three percent of experts favored the combination scenario. Dietetics education and experts' beliefs that assisted living facilities should be health promotion and maintenance facilities were significant predictors of emphases, including wellness considerations. Experts' personal views exerted a powerful influence.Experts chose food and nutrition service quality indicators that emphasized a focus on both wellness and amenities as their ideal scenarios for optimal food and nutrition services in assisted living facilities.
Practitioners' opinions on Food and Nutrition Care Indicators in assisted living facilities for older adults. - Journal of the American Dietetic Association
This study assessed the utility of the 57-indicator Food and Nutrition Care Indicators Checklist for assessing food and nutrition services in assisted-living facilities for older adults among registered dietitians (RDs). They were members of two American Dietetic Association practice groups focusing on aging and long-term care and were also employed in assisted-living facilities. The 1,281 respondents rated the importance of each checklist item and provided their views on the role of assisted-living facilities and their level of agreement with statements regarding the importance of residents' autonomy for making food choices and their ability to make wise dietary choices. Registered dietitians practicing in assisted-living facilities considered all of the domains on food and nutrition quality indicators on the Food and Nutrition Care Indicators Checklist to be highly important (92% of dining room environment items, 83% of foodservice operations, 92% of general nutrition, and 89% of therapeutic nutrition items). They preferred a service style that included both health and amenities, as did national health and aging experts. Registered dietitians should work with other professionals to further validate the checklist, promote its use, and establish optimal service models for food and nutrition services in assisted-living facilities for older adults.
Role of acetylcholinesterase and glutathione S-transferase following exposure to nicosulfuron and diazinon in Helicoverpa zea. - Ecotoxicology and environmental safety
The acute toxicity of diazinon combined with the herbicide nicosulfuron was determined using the corn earworm, Helicoverpa zea. Nicosulfuron significantly increased toxicity of diazinon to H. zea compared to diazinon alone based on dip bioassays to evaluate acute contact toxicity. Diazinon, an organophosphorous insecticide, controls insects by inhibiting acetylcholinesterase in the nervous system. Acetylcholinesterase activity was significantly altered in corn earworms exposed to binary mixtures compared to those exposed to diazinon alone; however, the activity did not correspond consistently with toxicity. Glutathione S-transferase (GST), also known to be altered by organophosphorous insecticides, did not exhibit significant changes following exposures to diazinon, nicosulfuron, or binary mixtures. Our results suggest that nicosulfuron increases toxicity of diazinon but the mechanism of toxicity does not appear to be correlated with acetylcholinesterase or GST inhibition.
Lead-induced alterations of apoptosis and neurotrophic factor mRNA in the developing rat cortex, hippocampus, and cerebellum. - Journal of biochemical and molecular toxicology
Previous reports have recently shown the prototypic neurotoxicant, lead, to induce apoptosis in the brains of developing organisms. In the current study, timed-pregnant rats were exposed to lead acetate (0.2% in the drinking water) 24 h following birth at postnatal day 1 (PND 1). Dams and pups were continuously exposed to lead through the drinking water of the dam until PND 20. Postnatal exposure in the pups resulted in altered mRNA levels of the following apoptotic and neurotrophic factors: caspase 2 and 3, bax, bcl-x, brain-derived neurotrophic factor (BDNF). Ribonuclease protection assays were conducted to measure the factors simultaneously at the following postnatal time points: 9, 12, 15, 20, 25, days. Our results suggest a brain region- and time-specific response following lead acetate exposure. The region most vulnerable to alterations occurs in the hippocampus with alterations beginning at PND 12, in which caspase 3, bcl-x, BDNF increase with lead exposure. Significant treatment effects were not observed for both the cortex and cerebellum.(c) 2007 Wiley Periodicals, Inc.
Food and nutrition care indicators: experts' views on quality indicators for food and nutrition services in assisted-living facilities for older adults. - Journal of the American Dietetic Association
This study assessed the views of 153 national experts in nutrition, health, and aging services in assisted-living facilities; including gerontological nutrition (39%), foodservice (14%), aging and disability (22%), geriatric medicine (9%), and assisted living (16%); on the practices that serve as indicators of the quality of food and nutrition services provided in assisted-living facilities and ascertained the most favored style of service delivery: health, amenities, or both. An 88-item Food and Nutrition Care Indicators survey was developed from assisted-living facility regulations in 50 states and other quality indicators of nutrition services. Respondents rated each item on a scale from 1 (not important) to 5 (extremely important). Results show that at least 80% of experts rated the majority of indicators in each domain as highly important (57% of dining room, 67% of foodservice indicators, 65% of general nutrition, and 70% of therapeutic nutrition indicators). Most experts (89%) rated a combination of indicators that included both health (general and therapeutic) and amenities service styles as being highly important. The 57 items rated most important were consolidated into a checklist. A service model that incorporates all of these elements appears to be most appropriate.
Reassessment of id1 protein expression in human mammary, prostate, and bladder cancers using a monospecific rabbit monoclonal anti-id1 antibody. - Cancer research
Id proteins are a class of dominant-negative antagonists of helix-loop-helix transcription factors and have been shown to control differentiation of a variety of cell types in diverse organisms. Although the importance of Id1 in tumor endothelial cells is well established, the expression and role of the Id1 protein in human cancer cells is controversial. To explore this issue, we developed and characterized a highly specific rabbit monoclonal antibody against Id1 to assess its expression in human breast, prostate, and bladder malignancies. Our results show that in usual types of human mammary carcinomas, the Id1 protein is expressed exclusively in the endothelium. Interestingly, we detected nuclear expression of the Id1 protein in the tumor cells in 10 of 45 cases of poorly differentiated and highly aggressive carcinoma with metaplastic morphology. Similarly, only 1 of 30 prostate cancer samples showed Id1-positive tumor cells, whereas in almost all, endothelial cells showed high Id1 expression. Intriguingly, whereas normal prostate glands do not show any Id1 protein expression, basal layer cells of benign prostate glands in proximity to tumors expressed high levels of the Id1 protein. In contrast to the lack of Id1 expression in the usual types of mammary and prostate cancers, the majority of transitional cell bladder tumors showed Id1 protein expression in both tumor and endothelial cells. These results suggest that further refinement of Id1 expression patterns in a variety of tumor types will be necessary to identify and study the functional roles played by Id1 in human neoplastic processes.
Time for assessment of nutrition services in assisted living facilities. - Journal of nutrition for the elderly
State regulations on the food and nutrition service components of care influence both care and service delivery of the elderly in assisted living facilities. Information on such regulations was abstracted from a survey of 50 states that had been carried out by the National Academy for State Health Policy. These data were supplemented by examining relevant state websites and by follow up phone calls. They were then evaluated using criteria recommended by expert groups. Forty-five states had some relevant food service and nutrition regulations, and five had no specific regulations. No state had regulations meeting all the criteria examined. The availability and completeness of food and nutrition regulations and standards in assisted living facilities may have life safety implications for older adults, and they deserve further evaluation.
